Abstract: COOLING APPARATUS               ABSTRACT OF THE DISCLOSURE An open loop, stepper-motor-driven, rigid magnetic disc memory apparatus for use with a data processing system A rigid magnetic disc with high track density is driven by a stepper motor in an open-loop fashion or without servomechanism control. The memory apparatus includes: band structure including a spring bias for coupling stepper motor drive to apparatus supporting magnetic heads above and/or below the spinning disc and for tem-perature compensating for disc/apparatus expansion and contrac-tion; manually operable control for zeroing the magnetic heads, moving and locking them in the disc's landing zone as, for example, while in transit, and providing a travel limit to head movement when the memory apparatus is operating; keying apparatus for preventing erroneous insertion and mis-alignment of and damage to an optical transducer relative to an optical mask arranged to spin with the disc structure; shim apparatus for precisely posi-tioning the magnetic heads in the spin axis direction; viscously-coupled inertia apparatus for damping the stepping motor's step-rotary motion; a device for employing spinning motion associated with the disc for cooling purposes; and other structure.

Granted: 1982-05-25
Abstract: ABSTRACT          The basic wear-lining of a steel converter is made of refractory material at least partly composed of burnt magnesite.  Maintenance is performed by spraying a refractory material onto this lining and/or coating the lining with slag.  The effect of this maintenance pro-cedure, in terms of the duration of the useful life of the lining, is improved if the particles of the magnesite component of the wear-lining contain on average more than 6-1/4 per cent monticellite.  In the past, material of this kind used on its own has not been found suitable for a wear-lining.

Abstract: Harshbarger, W.R. 2-23-6-5 DEVICE FABRICATION BY PLASMA ETCHING            Abstract of the Disclosure High density fine-line integrated structure fabrication is expedited by use of plasma etching systems which assure straight vertical walls (absence of undercutting).  Critical to the systems is choice of appropriate plasma chemistry.  Appropriate systems are characterized by inclusion of recombination centers, as well as active etchant species.  Recombination centers which effectively terminate etchant species lifetime in the immediate vicinity of resist walls afford means for controlling etching anisotropy.  Use is foreseen in large scale integrated circuitry (LSI) and is expected to be of particular interest for extremely fine design rules, i.e., in Very Large Scale Integrated circuitry.

Abstract: Draw Works Transmission Control Abstract A hydraulically operated draw works or the like has a hydraulically disengaged brake, a trans-mission, and a brake control valve.  A control for the hydraulic draw works includes an accumulator having a check valve connected between the brake control valve outlet and the brake to modulate the application of the brake after the brake has been fully released and to provide no modulation of brake application after the brake has been only partially released.  This minimizes shock in the draw works components when a load is lowered rapidly and yet provides rapid action when operated slowly.

In accordance with this invention, in the original manufacture of novolak resin, the procedure is modified so that instead of cool-ing the novolak resin after stripping to remove water, the novolak resin is neutralized to the pH above six by the addition of a ?asic material thereto either prior to or after stripping, and a sufficient quantity of furfuryl alcohol, or furfural monomeric solvent is added to solu-bilize and liquify the resulting novolak resin solution at ambient room temperature.  The resulting liquid novo-lak resin is storage stable.

Abstract: Abstract of the Disclosure The invention provides a protective casing for a cube-shaped modular ceramic heat exchanger core, in which the core can easily be installed without danger of leakage between the fluid paths of the core. To this end the core rests in the casing with the edges of one face engaged with a suitable ceramic fibre composition gasket; the opposite face of the same flow path is engaged by another such gasket and the gasket is in turn engaged by a gasket compression member.          The compression member is urged into this engagement by strong springs which thereby hold the gaskets in the necessary sealing engagment.  In one aspect of the invention the casing is readily changed to provide single or multi-pass of one of the flow paths through the core; such a casing consists of a central portion of the thickness dimension of the core and replaceable end portions which provide the inlet, outlet and respective plenums.  In another aspect of the invention the casing provides a central trunk with which a plurality of cores can be used selectively to provide increased heat exchange capacity without substantial increase in pressure drop.
